LDD's C.T.S. stands for Long Drive Daddy's Canton Trail Series . I came across this new trail system being built by Canton Township that connects several city parks and the Lower Rouge river trail. There is room for Biking, Jogging, and Walking. There is parking in tons of areas depending where you come from. Two good choices are in Flodin Park and Griffin park....
You are looking for a well hidden cache. Make sure that when you replace the cache, it is positioned in a way where it won't drop....you will know what I mean when you find it..LOL.
